For the incoming extra page size support for subpage (sectorsize < PAGE_SIZE) cases, the support for metadata will be a critical point. Currently for subpage support, we require 64K page size, so that no matter whatever the nodesize is, it will be contained inside one page. And we will reject any tree block which crosses page boundary. But for other page size, especially 16K page size, we must support nodesize differently. For nodesize < PAGE_SIZE, we will have the same requirement (tree blocks can't cross page boundary). While for nodesize >= PAGE_SIZE, we will require the tree blocks to be page aligned. To support such feature, we will make btrfs-check to reports more subpage related warnings for metadata. This patch will report any tree block which is not nodesize aligned as a warning. Existing mkfs/convert has already make sure all new tree blocks are nodesize aligned, this is just for older converted filesystems.
